Answer:
2) ∠SDH and ∠SDT are right angles because SD ⊥ HT.
3)
as it is given in the question.
4)
is the reflexive property.
5) ΔSHD ≅ ΔSTD by RHS congruency.
Step-by-step explanation:
Given in the question:

In ΔSHD and ΔSTD
(Given)
(SD ⊥ HT)
(Common)
Therefore,
(By RHS rule)
Reflexive property of congruency is defined as the property in which something is equal to itself. Hence, the reflexive property of these two triangles is 
Answer:
False
Step-by-step explanation:
Answer:
Step-by-step explanation:
1. 3x2 + 5x - 4 + 6x2 - x + 7
= combining like terms
= 9x2 + 4x + 3
2. 2y2 - 3y + 6 + y2 - 5y - 1 + (-4) + 2y2 - 2y
= 5y2 - 10y + 1
3. 2x2y - 3xy2 + x2y - 4x2y - 2xy2
= - x2y - 5xy2
4. x2 - y2 + 2x2 - 3xy + 4y2 + 3y2 - 5xy - x2
= 2x2 - 8xy + 6y2
First we have to find out how much green paint Anna lost by finding 2/5 and 3/10. 20 ÷ 5 = 4, 4 × 2 = 8 pints. 20 ÷ 10 = 2, 2 × 3 = 6 pints. 8 + 6 = 14 pints. 20 - 14 = 6 pints left. If she needs 12 3/4 pints in total, then you just have to do 12 - 6 to get 6 3/4 pints more that you need. I hope this helps!
The Answer To Your Question Would Be 12
